I wish HN had a "wow" button. Simply upvoting a submission like this one seems... inadequate.

Inside sources say that it will be called Nitendo 3DS

Context: GelSight can register “physical features less than a micrometer in depth and about two micrometers across,” which means it can create a 3D image of ink on a piece of paper (below):

Below that there is a 3D image of ink on a piece of paper. Taken with a handheld device. "Wow" about covers it, although I might go with "WOW."

The computer vision part might be related to polynomial texture mapping: http://www.hpl.hp.com/research/ptm/

I wonder how easy a cheap, low tech version of this would be to make. A camera staring at the underside of a clear gel with an incredibly thin layer of opaque reflective pigment on top of it could pick up and translate a depth map if the surface were evenly lit.

That's an awesome idea. Perhaps it could kick in at a karma level.

"When the metallic side is pressed against the surface of an object, the rubber deforms slightly"

while the concept is great, it still doesn't maximize precision (for high resolution analysis), since the pressure can also deform your object of interest. ideally, you would want to use a metallic as less viscous as possible to keep the surfaces rigid.
